Who am I?
I'm Pascal Perrenoud, a software engineer in Yverdon-les-Bains. I have a BSc from HEIG-VD and an MSc from HES-SO, both in cybersecurity. I spent three years in research and engineering, two as a teaching and research assistant at HEIG-VD and then my master's thesis at CSEM, before founding Codexa to build software full time. Rust is my language of choice; security is the habit I bring to everything I build. Outside work, I play music.
